Which statement about repair manuals and testing plans is correct?

• A. Neither
• B. A only
• C. B only
• D. Both A and B

Answer: (B)

Focus on how a proper repair is carried out and verified. A repair manual gives you the exact steps, torque values, wiring details, and safety notes needed to perform the repair correctly. After the repair is done, a testing plan provides the defined tests, expected results, and pass/fail criteria to verify that the repair actually worked and that the system operates within specification. The correct statement is the one that recognizes this sequence: follow the documented repair procedure, then use the testing plan to confirm the outcome. The other assertion—whatever it says about not needing one or both of these documents—conflicts with how repairs are reliably validated in practice. So, the emphasis is on using the manual for the repair and the testing plan for verification to ensure a correct, verifiable result.
